. Application filed OctoberlI, 1926, SerialNo.

The present inventionrelates to a self registering andticket-distributing peoplesbalance of the kind in which the devices forregistering the'weight on a ticket, forcockmg a stamping-hammer and for.e ecting the ticket are started by the dropped coin'and by the weight ofthe personon the platform.

The novelfeature of the present invention consists in a cocking deviceof the stamping hammer which is controlled bya spring barrel and isarranged in such a way that an overstraining of. the springis' reventedin thecase of any irregular'handling the barrel 5.

In the drawing-13 designates the stamping hammer of a weighing andrecording scale joined to the and 5, 6 a spring barrel mounted loose'onan axle 3 supported in bearings 1, 2 by a casing 26. One of these sidewalls of this barrel is formed like a ratchet wheel 5., while a somewhatsmaller ratchet 4 having its teeth set in a contrary sense is fast on asquaredpart of the axle 3 and is worked in an anti-clockwise sense by afinger 16 provided at the end of a rod 15 attached to the platform ofthe scale in order to'bend the spiral spring 7 of The rod 15 as shown inFig. 4 is attached to the one arm of a T lever 39 which is pivoted at 40and is supporting with another arm the platform. 41 of the scale in sucha manner that the loading of the platform will cause an upward movementof the rod .15 and thereby a feeding movement of the pawl 16. Astationary pawl 18 pivoted'at 17 prevents ratchet .4

from falling back and another pawl 19 provided at the one arm of anangular lever 21 blocks the ratchet 5 and extends with a lengthened part119 and with some play behind one of the teeth of the ratchet 4. The

other arm of this lever isengaged with its cylindrically shaped end 22in the bifurcated arm of an angular pivoted lever 24 which leans withhis other arm against the finger 16. I The two face plates'of the barrelare held together by a trundle gearing formed by screw bolts 8 providedwith rollers 9. Said trundles are adapted to engage the tail 14 of andloaded again.

the stamping hammer-13 pivoted on an axle I 11. Fast to the hubh of saidhammer is also, an arm lOto theend of which is attached anv upwardly.directed 't'e'nsion spring 27 and y in. apdownward direction a rod-28.This rod as shown in Fig. 4is ending in a hook 34 engaging a hook 35- atthe end of bar '36 suspended at-33;whichgbaris hinged to a weightedlever-pivoted at 37. Bar-1 36 will be moved sideways so as to free hook34 from h'ook 35 when a'coin'is strikingthe 21111138 of said weightedlever. WVhile t-he hooks 34' and 35 are engaged the rod 28 maintains thehammer in its. uplifted; cocked position.

Fast to the same hublofthe hammer is also a toothed segment 29.geared:with anothersegment 30 unto which. is attached a carrier 31,fadaptedto forward the, tickets into the" path' of 'the stamping hammepj Finally loose on said aXle 11 is mounted a stationary pawl 12 havinga lateral projection 25 arranged in such a way that the arm of the Istamping hammer 13 when rising will take said pawl along with it so asto disengage it from the ratchet 5. attached to one arm of the lever 21secures the constant contact of the pawls 119 and 19. with the surfacesof the respective ratchets.

The working ofthis cocking device is as follows The Fig. 2 representsthe cooked position I, A traction spring 32 of the hammer. It issupposed that the ham mer be in'its uncocked position and the balance inits position of rest. The barrel 5, 6 will be locked in this position bythe pawl 19;engaging the ratchet5... Therefore if they I platform notshown, is loaded the angular lever 24 will be positioned such that thefinger 16 turns the axis 3 by means of the ratchet 4 so .as to bendthereby spring 7.

The moving ratchet 4 disengages the pawl 19 from the ratchet 5- andsimultaneously therewith also the finger 16"will. be disengaged from theratchet 5' by means of the angular lever 24, while pawl 18 blocks theratchet 4. 7

Now the barrel 5, 6 will be turned so far as the play between thestationary pawl 12 and i the next tooth of the ratchet 5 will allow andthereby pawl 19 will be raised so as to bear on a tooth of the ratchet5" and will be pre vented thereby from falling in.' Therefore also thefinger 16 will remain disengaged even if the platform would becomeunloaded The purpose of this ar rangement is to prevent anyoverstraining of the spring 7 by any irregular handling of 2.

the scale. In the lowered position of the hammer however thearm will beraised so far that the pawl 12 becomes disengaged from its engagementwiththe ratchet5 by means of the projection 25 and the barrel willbecome operative and will turn so as to cause a roller 9 of the trundlegearing to operate the tail 14 of the hammer which will assume theposit-ion shown in Fig. 2. The

barrel will then turn until the next tooth of the ratchet 5"gets'sto'pped by the pawl 19, But 'as this pawlhas again fallen in alsothe :finger 16 has fallen in and likewise the pawl 12 into the ratchet4: but vat a certain' distance from the next tooth and the tail let'willremain half-ways betweentwo rollers of the trundle gearing. f The hammer42 will be maintained' in this cocked position by releasing means notshown and not forming part of this invention. a
